Big Tech’s AI Boom Is Jacking Up Your Electric Bill—And the System Is Letting It Happen

Big Tech’s AI boom is draining the U.S. power grid—and sticking ordinary households with the bill. The latest PJM Interconnection auction results are a brutal wake-up call. For the third time in a row, capacity prices hit the legal ceiling. Supply fell short of what’s needed to keep the grid stable. This isn’t just a market imbalance. It’s a rigged system that shifts costs from demand drivers to people who can least afford it.
Official records tell a straightforward story. On July 14, PJM—serving 67 million people across 13 states—announced its 2028-29 capacity auction cleared at $325 per megawatt-day. That’s the maximum allowed under its price cap. Supply fell 6.8 gigawatts short of reliability needs. Moody’s Ratings, in a July 22 sector report, spelled out the root cause. It said the current system lacks mechanisms to make new large users pay for new supply. The industry subtext here is impossible to miss. Moody’s doesn’t weigh in on fairness for fun. It’s warning bond investors that PJM’s rules are out of step. Other U.S. power markets require big customers to sign direct contracts covering new generation costs. PJM doesn’t.
Official data paints a grim picture of demand and costs. PJM hit a peak demand record of 168.2 gigawatts on July 2. That’s nearly 3 GW above a mark set almost two decades earlier. Yet new generation capacity from the auction fell to just 525 megawatts. That’s roughly half of what cleared six months prior, per Syso Technologies’ analysis. PJM’s market monitor found $6.3 billion of the $16.4 billion in auction charges comes directly from data center demand. Over four auctions, that total hits $29.4 billion, per The Hill. Without the price cap, PJM’s simulation shows prices would hit $554.72/MW-day. In Chicago’s ComEd zone, that number jumps to $776.69. This isn’t just spreadsheet math. Consumer Reports documented an Ohio resident whose bill hit $281 this past January. Utilities claim ratepayers won’t foot AI’s bill. But Harvard Law’s Electricity Law Initiative identified two clear cost channels. Utilities spread new infrastructure costs across all users. Market-based capacity prices rise because supply can’t keep up with data center demand. Both were visible in PJM’s July auction. Reuters reports ICF projects rate hikes of up to 60% over five years for PJM customers.
PJM’s request for an emergency September auction is a quiet admission the market isn’t working. Lawmakers in multiple states are pushing back against rising bills and utility profits. Some analysts propose forcing hyperscalers to sign long-term supply contracts. But adoption is uneven, and PJM still lacks the direct-contract rules other markets use. Until PJM fixes its system to make Big Tech pay for the power its AI centers consume, residential bills will keep climbing, and grid reliability will continue to erode.
